The information given on a Type 3.1/3.2 Inspection Certificate are actual test results from the material in the lot from which the steel products have been supplied (formally referred to as "specific testing"). A 3.1 Inspection Certificate is endorsed only by the manufacturers own representative who has to be independent from the manufacturing process (Test House Manager) whilsta 3.2
Inspection Certificate has additionally been countersigned by an independent inspectionauthority who has confirmed that the testing and inspection process demanded by the specification have been adhered to correctly.
The main difference between 3.1 and 3.2 certification in materials is the level of control and inspection conducted. A 3.1 certification includes both the material test report and inspection certificate, whereas a 3.2 certification includes additional verification by an independent third party. This extra level of scrutiny provides higher assurance of the material's quality and compliance with standards.
